LOCKEFORD - The San Joaquin County Sheriff's Office took down a major pot-growing operation Wednesday, seizing more than $200,000 worth of marijuana and several firearms, authorities said.

The San Joaquin County Metro Narcotics Task Force on Wednesday morning served a search warrant in the 12800 block of East Victor Road in Lockeford, about six miles east of Highway 99, deputies said.

A large warehouse on the property contained six rooms that were being used to grow marijuana, authorities said. The operation was being powered by stolen electricity, officials said. Authorities seized more than 50 pounds of marijuana, including 37 mature plants, as well as seven guns and a small amount of methamphetamine, deputies said.

Bradley Frechette, 54, was arrested on suspicion of cultivation and possession of marijuana for sales, possession of methamphetamine, theft of utility services and possession of a firearm in commission of a felony, authorities said. He is being held at the San Joaquin County jail in lieu of $430,000 bail, deputies said.

Dessa Frechette, 42, was arrested on suspicion of methamphetamine possession, authorities said. She was booked at the County Jail and released, according to jail records.

"There are multiple crimes here - not only the cultivation and sales of marijuana, but you also have the theft of electricity," said Deputy Les Garcia, a spokesman for the Sheriff's Office. "Any time we come across an operation as elaborate as this, and any time we make this type of an arrest, it is significant, especially to the neighboring residents and businesses."
